Description

Technical Field

[0001] This invention relates to the field of structural engineering technology, and in particular to a concrete frame structure with a protective layer and its construction method. Background Technology

[0002] In the field of structural engineering, concrete structures can develop cracks during construction and service, which can lead to a decrease in the durability of the concrete structure, affecting its normal use or shortening its service life.

[0003] Especially in large-span frame structures such as airport terminals, the bending moments at the ends of frame beams are relatively large. When using ordinary concrete, the tensile strength and ultimate tensile strain are both relatively small, making the top of the beam ends prone to concrete cracking. Figure 23 and Figure 24 This diagram illustrates common crack patterns at the ends of side spans and mid-span beams. Effectively controlling the crack width at the ends of frame beams and slabs has long been a challenging problem in the engineering field.

[0004] In existing technologies, methods such as increasing the longitudinal reinforcement and setting prestressed reinforcement in the frame beams are commonly used to reduce the width of cracks at the top of the beam and slab ends. However, existing technologies usually result in increased steel consumption, excessively dense reinforcement which is not conducive to ensuring construction quality, and regular column grid layout and complex structure in actual projects. These drawbacks lead to increased construction costs, difficulties in the construction process, and low construction efficiency.

[0005] In recent years, some high-ductility materials have emerged, such as FRP (Fiberglass-Rainforced Plastics) fiber composites, UHPC (Ultra-High Performance Concrete) ultra-high performance concrete, and ECC (Engineered Cementations Composite) fiber-reinforced cement-based composites. Because they have good tensile strain hardening properties, ultra-high toughness and excellent crack control capabilities, they are used as protective layers in the construction and reinforcement and repair of buildings, bridges, highways, tunnels and other engineering projects.

[0006] Unlike ordinary reinforced concrete components, when high-ductility materials are coated on the surface of reinforced concrete (especially the top of beams and slabs) that is prone to cracking, only many fine and dense cracks are formed under tension. This increases the surface toughness of the reinforced concrete, which not only effectively prevents the formation of large cracks, but also reduces the penetration of external water and chloride ions into the interior of the reinforced concrete frame structure through large cracks, thus reducing damage to the longitudinal structure of the building and improving the durability of the building structure.

[0007] Currently, in construction, high-ductility materials are typically applied directly to the outer surface of the reinforced concrete frame of an already erected and poured building structure. However, due to insufficient adhesion between the high-ductility material and the reinforced concrete frame, it cannot truly form an integrated structure. This reduces the protective effect of the high-ductility material layer on large-span concrete frame structures. Consequently, even with the protection of the high-ductility material, the crack resistance and durability of large-span reinforced concrete frame structures still fail to meet design requirements, and the overall service life of the building does not meet expectations.

[0008] Therefore, although high-ductility materials have excellent crack resistance, their practical applications are severely limited due to the factors mentioned above. Summary of the Invention

[0009] Based on the above analysis, the present invention aims to provide a concrete frame structure with a protective layer and its construction method, in order to solve the technical problem that the crack resistance and durability of large-span reinforced concrete frame structures cannot meet design requirements and the service life is reduced due to the poor integration of high-ductility materials and concrete frame structures.

[0070] The following is combined with Figures 1-22 The technical solution of the present invention will be described in more detail below.

[0071] In this embodiment of the invention, the top surface of the concrete frame structure is defined as upward, the foundation direction as downward, the outer perimeter of the concrete frame structure as outward, and the portion within the outer perimeter as inward. The cross-sectional width of each column is greater than the cross-sectional width of each beam 22.

[0072] Meanwhile, in this embodiment of the invention, the reinforced concrete section is defined as a three-dimensional concrete frame structure with three spans each in the horizontal and vertical directions.

[0073] In this embodiment of the invention, ECC (Engineered Cementations Composite), a fiber-reinforced cementitious composite material with good adhesion, is selected as the material for the protective layer component 3.

[0074] Example 1

[0075] A concrete frame structure with a right-angled protective layer.

[0076] The protective layer material is ECC, which has an equal wall thickness structure; the right-angle structure protective layer refers to multiple planes that make up the protective layer intersecting perpendicularly.

[0077] like Figure 1 As shown, the concrete frame structure with an ECC material layer in this embodiment 1 includes a reinforced concrete section and a protective layer assembly 3; the reinforced concrete section includes a column assembly 1 and a beam-slab assembly 2; a concrete frame settlement section is provided on the outer surface of the reinforced concrete section; the high-ductility material of the protective layer assembly 3 is filled in the concrete frame settlement section; the protective layer assembly 3 is bonded to the reinforced concrete section, and the surface of the protective layer assembly 3 includes a protective layer adhesive surface and a protective layer outer surface; the protective layer adhesive surface is bonded to the surface of the concrete frame settlement section, and the protective layer outer surface is flush with the outer surface of the reinforced concrete section.

[0078] The beam-slab assembly 2 has three layers, from bottom to top: bottom beam-slab, middle beam-slab, and top beam-slab.

[0079] like Figure 4 As shown, the bottom beam slab, middle beam slab and top beam slab of beam slab assembly 2 have the same structure, each including multiple floor slabs 21 and beams 22, and the floor slabs 21 and beams 22 are cast into one piece.

[0080] like Figure 2 As shown, the column assembly 1 includes multiple corner columns 11, side columns 12, and central columns.

[0081] Among them, the corner column 11 and the side column 12 are both integral columns from the foundation to the top.

[0082] The central column is composed of multiple column segments with interlayered protective layers, including a central column 13 and a foundation column 14. The foundation column 14 is located in the foundation portion of the concrete frame structure. The upper structure of the foundation column 14 is the same as that of the central column 13, but the lower end of the foundation column 14 is shorter than that of the central column 13.

[0083] In this embodiment, the cross-sectional width of each column of the column assembly 1 is greater than the cross-sectional width of the beam 22.

[0084] A concrete frame settlement section is provided on the outer surface of the joint between the column assembly 1 and the beam-slab assembly 2 of the reinforced concrete section; the protective layer assembly 3 is provided on the concrete frame settlement section. The protective layer assembly 3 is bonded to the reinforced concrete section, and the surface of the protective layer assembly 3 includes a protective layer adhesive surface and a protective layer outer surface; the protective layer adhesive surface is bonded to the surface of the concrete frame settlement section, and the protective layer outer surface is flush with the outer surface of the reinforced concrete section.

[0085] Combination Figure 1 and Figure 2 As shown, the protective layer assembly 3 includes a beam-slab protective layer unit 31 and a beam-slab-column protective layer unit 32.

[0086] The following describes the beam-slab protective layer unit 31 and the related structures on the column assembly 1 and beam-slab assembly 2 used for the settlement beam-slab protective layer unit 31:

[0087] The beam-slab protective layer unit 31 is disposed on the upper surface of the beam-slab assembly 2, specifically at the junction of the upper horizontal surface of the beam-slab assembly 2 and the column cross-section of the column assembly 1, and is used to bond the floor slab 21, the beam 22 and the column of the column assembly 1 in the horizontal direction.

[0088] Combination Figure 1 and Figure 2 As shown, the beam-slab protective layer unit 31 of this embodiment 1 includes a middle upper beam-slab protective layer 311, a side upper beam-slab protective layer 312, and a corner upper beam-slab protective layer 313.

[0089] like Figure 1 and Figure 8As shown, the protective layer 311 of the middle upper beam plate is an ECC material layer with a cross structure. In this embodiment, the protective layer 311 of the middle upper beam plate is set in the middle of the upper surface of each beam plate of the beam plate assembly 2, specifically at the upper surface of the intersection of the four crossbeams 22, and coincides with the center position of each middle section column 13 / foundation column 14 of the middle column.

[0090] Three intermediate columns 13 are stacked on the base column 14 at the bottom, and the middle upper beam slab protective layer 311 is placed between them.

[0091] Preferably, the width of the middle upper beam plate protective layer 311 is greater than the width of the crossbeam 22, so that the middle upper beam plate protective layer 311 extends from the crossbeam 22 to cover the floor slab 21, and is used to bond the connection between the crossbeam 22 and the floor slab 21, protecting the position that is prone to destructive cracks.

[0092] Preferably, the length of the middle upper beam plate protective layer 311 is not less than 5 times the width of the middle upper beam plate protective layer 311, so as to cover the part of the crossbeam 22 that is prone to cracking along its length.

[0093] like Figure 3 As shown, correspondingly, a middle upper beam settlement groove 23 and a beam column passage groove 24 are provided at the middle position of the upper surface of each beam of the beam assembly 2.

[0094] The beam-slab columns are installed through slots 24 at each column of the column assembly 1. The slots 24 are used to install the foundation columns 14 and the intermediate columns 13 below.

[0095] The middle upper beam slab settlement groove 23 is set around each beam slab column through the groove 24, namely the middle upper beam slab settlement groove 231 located at the foundation column 14 / middle section column 13 and the side middle upper beam slab settlement groove 232 located at the side column 12.

[0096] The middle upper beam slab settlement groove 23 is used to fill the T-shaped vertical line portion of the middle upper beam slab protective layer 311 and the side upper beam slab protective layer 312 with ECC filler. Specifically, the corner middle upper beam slab settlement groove 231 is used to fill the corner upper beam slab protective layer 313 with ECC filler, the side middle upper beam slab settlement groove 232 is used to fill the side upper beam slab protective layer 312 with ECC filler, and the middle upper beam slab settlement groove 233 is used to fill the middle upper beam slab protective layer 311 with ECC filler.

[0097] Figure 12 It shows Figure 2 The horizontal section at the height of point E is located at the mid-section column 13 / foundation column 14.

[0098] The top of the base column 14 and the middle column 13 is lower than the thickness of the middle upper beam slab protective layer 311 on the upper surface of the beam-slab assembly 2. The base column 14 and the middle column 13 have the same structure but different lengths.

[0099] like Figure 7 As shown, correspondingly, multiple column-settlement grooves 111 are provided on the upper side of the middle column 13 / foundation column 14. Specifically, in this embodiment, two column-settlement grooves 111 are symmetrically provided on each side of the upper end of the middle column 13 / foundation column 14 to fill the ECC material layer of the protective layer 311 of the middle upper beam slab.

[0100] The upper end of the middle column 13 / foundation column 14 is lowered vertically by the height of one column-settlement trough 111 (which is also the middle upper beam slab protective layer 311) relative to the upper surface of the beam slab at that location.

[0101] like Figure 1 and Figure 9 As shown, the protective layer 312 of the side upper beam slab is an ECC material layer with a T-shaped structure. Specifically, the protective layer 312 of the side upper beam slab is located at the center of the side column 12 in the middle of the perimeter of each beam assembly 2. The T-shaped structure of the protective layer 312 of the side upper beam slab includes two support plates of the T-shaped horizontal beam and one support plate in the vertical position of the T.

[0102] Preferably, the length of the three support plates of the side upper beam plate protective layer 312 is not less than five times the width of the side upper beam plate protective layer 312, so as to cover the part of the crossbeam 22 most prone to cracking along its length. The outer side of the T-shaped crossbeam of the side upper beam plate protective layer 312 is flush with or extends beyond the outer edge of the crossbeam 22 by the thickness of the outer beam plate column protective layer 322.

[0103] Preferably, the width of the three support plates of the side upper beam plate protective layer 312 extends beyond the crossbeam 22 onto the floor slab 21 in the direction facing the floor slab 21, so that the side upper beam plate protective layer 312 extends from the crossbeam 22 to cover the floor slab 21, and is used to bond the connection between the crossbeam 22 and the floor slab 21 to protect the location that is prone to destructive cracks.

[0104] like Figure 3 As shown, correspondingly, upper beam edge settlement grooves and beam column passage slots 24 are provided around the upper surface of the beam-slab assembly 2.

[0105] The upper beam slab edge settlement groove includes a first upper beam slab edge settlement groove 25 and a second upper beam slab edge settlement groove 28. The first upper beam slab edge settlement groove 25 and the second upper beam slab edge settlement groove 28 form a continuous T-shaped structure.

[0106] The beam and slab columns arranged around the beam and slab assembly 2 are provided through the slot 24 for the side columns 12 and the corner columns 11 to pass through; the upper beam and slab side settlement groove is used to set the side upper beam and slab protective layer 312 and the corner upper beam and slab protective layer 313.

[0107] like Figure 6 As shown, the side column 12 is an integral structure, with a side connection part of the side column at the top and a column three-settlement groove 113 in the middle.

[0108] The three settlement grooves 113 of each column in the middle of the side column 12 are groove structures with openings on three sides inward. They are used to fill the middle layers of each side column 12, including the bottom layer and the ECC material layer of the upper beam plate protective layer 311 in the middle position.

[0109] The side connection part of the side column 12 is located on the outer side of the top of the side column 12, specifically a straight-line outer side connection part 121. The height of the outer side connection part 121 is equal to the height of the protective layer 312 of the side upper beam plate, and the thickness of the outer side connection part 121 is equal to the difference in horizontal section between the side column 12 and the crossbeam 22 on the same side. The area of ​​the top of the side column 12 excluding the outer side connection part 121 has the same volume as the area of ​​the column's three settlement grooves 113.

[0110] The side columns 12 are integrally connected on one side of the outer perimeter of the structure, making the side columns 12 an integral structure.

[0111] like Figure 1 and Figure 10 As shown, the corner upper beam slab protective layer 313 is an ECC material layer with an L-shaped structure of equal length on both sides. Specifically, the center position of the L-shaped structure of the corner upper beam slab protective layer 313 is set at the center position of the side column 12 at each corner of the beam slab assembly 2. There are two support plates on both sides of the L-shaped structure of the corner upper beam slab protective layer 313.

[0112] Preferably, the length of the two support plates of the corner upper beam plate protective layer 313 is not less than 5 times the width of the corner upper beam plate protective layer 313, so as to cover the part of the crossbeam 22 that is most prone to cracking along its length. The outer side of the L-structure of the corner upper beam plate protective layer 313 is flush with the outer edge of the crossbeam 22 that is perpendicular to it at its location.

[0113] Preferably, the two support plates of the corner beam slab protective layer 313 extend beyond the beam 22 to the floor slab 21 on one side of the interior of the concrete frame structure, so that the corner beam slab protective layer 313 extends from the beam 22 to cover the floor slab 21, and is used to bond the connection between the beam 22 and the floor slab 21, protecting the location most prone to destructive cracks.

[0114] Preferably, the ECC material layer of the corner upper beam slab protective layer 313 can be combined with the side upper beam slab protective layer 312 located at the same column position to form an integral corner protective layer. The top of this integral corner protective layer is flush with the top of the connected beam slab assembly 2, and the side is flush with the side facade of the connected beam slab assembly 2.

[0115] like Figure 5 As shown, correspondingly, the corner columns 11 are provided with column three settlement grooves 113 on the upper surface of each layer of beam and slab assembly 2 to fill the ECC material of the corner beam and slab protective layer 313.

[0116] like Figure 6 As shown, the corner column 11 is an integral structure, with a side connection part of the corner column 11 on its top and a column three settling tank 113 in its middle.

[0117] The corner column 11 has a three-sided settlement groove 113, which is a groove structure with openings on both sides. It is used to partially fill the corner beam slab protective layer 313 on the corner column 11 with ECC material. The two openings of the corner column settlement groove 113 face the interior of the concrete frame structure.

[0118] The side connection portion of the corner column 11 is located at the top of the corner column 11. Specifically, it is a corner column outer side connection portion 116 located on the two outer sides of the top of the corner column 11. The corner column outer side connection portion 116 is equilateral L-shaped. The height of the corner column outer side connection portion 116 is equal to the height of the protective layer 313 of the upper beam slab at the corner. The thickness of the corner column outer side connection portion 116 is equal to the difference in horizontal section between the corner column 11 and the crossbeam 22 on the same side. The area at the top of the corner column 11 excluding the corner column outer side connection portion 116 has the same volume as the area contained in the column three-settlement tank 113.

[0119] The two adjacent outer sides of the corner column 11 are connected as a whole, making the corner column 11 a single structure.

[0120] The following describes the beam-slab-column protective layer unit 32 and the related structures on the column assembly 1 and beam-slab assembly 2 used for the settlement beam-slab-column protective layer unit 32:

[0121] The beam-slab-column protective layer unit 32 is located at the junction of the corner column 11 / side column 12 and the beam-slab assembly 2, specifically at the junction of the lower facade of the beam-slab assembly 2 and the column body of the corner column 11 / side column 12, and is used to bond the floor slab 21, beam 22 and the column body of the corner column 11 / side column 12 in the vertical direction.

[0122] Combination Figure 2 , Figure 11 , Figure 14 and Figure 16As shown, the beam-slab-column protective layer unit 32 of this embodiment 1 includes an inner beam-slab-column protective layer 321 and an outer beam-slab-column protective layer 322.

[0123] like Figure 16 As shown, the outer beam-slab-column protective layer 322 is an L-shaped curved plate structure, including an outer beam-column surface protective layer 3221 and an outer beam-column beam surface protective layer 3222. The outer beam-slab-column protective layer 322 is located at the junction of the corner column 11 / side column 12 and the beam-slab assembly 2 on the outer perimeter of the concrete frame structure. Specifically, the outer beam-slab-column protective layer 322 is located at the junction of the outer edge side facade of the corner column 11 / side column 12 and the outer edge side facade of the beam-slab assembly 2.

[0124] like Figure 14 As shown, the protective layer 3221 on the outer beam column surface is relatively short and is a cuboid.

[0125] Preferably, the shorter side of the rectangular outer beam-column protective layer 3221 is not less than 5 times the thickness of the outer beam-column protective layer 3221, to cover the parts of the corner columns 11 / side columns 12 most prone to cracking. The longer side of the rectangular outer beam-column protective layer 3221 is the height of the outer beam-column protective layer 322.

[0126] like Figure 5 and Figure 6 As shown, the ECC material layer in the column settlement groove 112 set on the corner column 11 / side column 12 corresponding to the outer beam column protective layer 3221 is used to fill the outer beam column protective layer 3221.

[0127] like Figure 14 As shown, the outer beam and column protective layer 3222 is relatively long, and its planar projection is a right-angled trapezoidal structure with the right-angled waist side on top and the oblique-angled waist side on the bottom. The long bottom edge of the outer beam and column protective layer 3222 connects to the long side of the outer beam and column protective layer 3221, and is located at the root of the junction of the corner column 11 / side column 12 and the beam and slab assembly 2. The purpose is to lay out a large area of ​​outer beam and column protective layer 322 at the location where cracks are most likely to occur.

[0128] Preferably, the length of the protective layer 3222 on the surface of the external beam and column is not less than the length of the short side of the cuboid and not less than 5 times the height of the protective layer 322 on the external beam and column, in order to cover the part of the external beam facade of the concrete frame structure that is most prone to cracking.

[0129] Figure 17 It shows Figure 2 The longitudinal section view at point E next to the corner column is a schematic diagram of the cross section of the floor slab 21, the beam 22 and the protective layer component 3 at that location.

[0130] like Figure 3As shown, corresponding to the outer beam and column surface protective layer 3222, the periphery of the beam and slab assembly 2 is provided with corner side beam and slab settlement grooves 26, which are used to fill the ECC material layer of the outer beam and column surface protective layer 3222.

[0131] The corner side beam plate settlement groove 26 and the column second settlement groove 112 are connected, and the inner cavity structure matches the outer beam plate column protective layer 322.

[0132] The corner side beam plate settlement groove 26 and the column second settlement groove 112 are connected to the column third settlement groove 113, so that the outer beam plate column protective layer 322 and the side upper beam plate protective layer 312 / corner upper beam plate protective layer 313 are bonded into a whole.

[0133] like Figure 11 As shown, the inner beam-slab-column protective layer 321 has three mutually perpendicular intersecting facades: the inner beam-column top slab protective layer 3211, the inner beam-column beam surface protective layer 3212, and the inner beam-column column body protective layer 3213, forming a box-shaped structure. The inner beam-slab-column protective layer 321 is located at the non-edge location of the concrete frame structure, at the junction of the corner columns 11 / side columns 12 / 13 / 14 and the non-outer edge facade of the beam-slab assembly 2. Specifically, the inner beam-slab-column protective layer 321 is located below the floor slab 21 in the beam-slab assembly 2, on the non-edge facade of the beam 22, and at the junction of the non-outer edge facades of the corner columns 11 / side columns 12 / middle column 13 / foundation column 14.

[0134] like Figure 11 As shown, the inner beam-column top slab protective layer 3211 and the inner beam-column body protective layer 3213 are orthogonal and are both rectangular plate-like structures. Among them, the inner beam-column top slab protective layer 3211 is longer than the inner beam-column body protective layer 3213. The width of both is the same, which is equal to the thickness of the inner beam-column protective layer 321.

[0135] like Figure 11 As shown, the inner beam-column protective layer 3212 is a plate-like structure with a right-angled trapezoidal planar projection. The right-angled waist side is on top and is the same length as the inner beam-column top plate protective layer 3211. The right-angled trapezoidal base is on the inner beam-column body protective layer 3213 and is the same length as the long side of the inner beam-column body protective layer 3213.

[0136] Combination Figure 4 Corresponding to the inner beam-slab-column protective layer 321, the surface of the floor slab 21 below the beam-slab assembly 2 and the side elevation of the beam 22 are in contact with...

[0137] A middle side beam plate settlement groove 27 is provided at the junction of each column of the column assembly 1 to fill the ECC material layer of the inner beam column surface protective layer 3212 and the inner beam column body protective layer 3213.

[0138] Specifically, at the location of the beam-slab assembly 2 on each floor, there are 2 middle beam-slab settlement grooves 27 at the intersection with the corner column 11, 4 middle beam-slab settlement grooves 27 at the intersection with the side column 12, and 8 middle beam-slab settlement grooves 27 at the intersection with the middle column 13 / foundation column 14.

[0139] Combination Figure 5 , Figure 6 and Figure 7 As shown, corresponding to the inner beam-slab-column protective layer 321, each column of the column assembly 1 is provided with multiple column-settlement grooves 111 at the junction with the beam-slab assembly 2, which are used to fill the ECC material layer of the inner beam-column top plate protective layer 3211.

[0140] Specifically, at the matching positions of the beam-slab assembly 2 on each layer and the settlement groove 27 of each middle and side beam-slab, the corner column 11 is provided with 2 column-settlement grooves 111, the side column 12 is provided with 4 column-settlement grooves 111, and the upper end of the middle column 13 / foundation column 14 is provided with 8 column-settlement grooves 111.

[0141] Preferably, the width of the inner beam-column protective layer 3213 is five times its thickness, and the length of the inner beam-column top slab protective layer 3211 and the inner beam-column beam surface protective layer 3212 is not less than five times the thickness of the inner beam-column protective layer 321. This arrangement ensures that the three mutually perpendicular intersecting facades of the inner beam-column protective layer 321 effectively cover the areas where cracks may occur at the intersection of each column of the column assembly 1 and the interior of each layer of the beam-slab assembly 2.

[0142] Figure 13 It shows Figure 1 The longitudinal section of the beam-slab assembly and protective layer assembly in the FF direction.

[0143] In this embodiment 1, after the ECC filler of the outer beam and column protective layer 322 is filled into the settlement groove 26 of the corner side beam and the column two settlement groove 112 on the corner column 11 / side column 12 around the concrete frame, it is bonded to the side upper beam and upper beam protective layer 312 / corner upper beam and upper beam protective layer 313 filled in the settlement groove of the upper beam and upper beam at the corresponding position to form a whole.

[0144] Furthermore, in this embodiment, all concrete frame settlement surfaces are provided with reinforced concrete retaining portions, such that the protective layer bonding surfaces of the protective layer components 3 filled therein form protective layer bonding surface retaining portions that match the structure of the reinforced concrete retaining portions.

[0145] Taking the settlement groove 27 of the middle side beam slab on beam-slab assembly 2 as an example, the reinforced concrete retaining part set on the surface of the settlement part of the concrete frame is described as follows:

[0146] like Figure 18 and Figure 19 As shown, an inner beam-slab column protective layer retaining part 321′11 is provided on each bonding surface of the middle beam-slab settlement groove 27, forming a middle beam-slab settlement groove 27′1 with a retaining part. The middle beam-slab settlement groove 27′1 with a retaining part is used to fill the ECC material layer of the inner beam-slab column protective layer 321′1 with a retaining part.

[0147] In this embodiment 1, the bonding surfaces of the middle side beam plate settlement groove 27′11 with the retaining part are arranged in parallel straight lines.

[0148] Preferably, the three orthogonal surfaces of the middle side beam plate settlement groove 27′1 with the retaining part are provided with straight protrusions of different directions, which serve as the middle side beam plate settlement groove retaining parts 27′11.

[0149] Preferably, the straight protrusion of the middle beam slab settlement groove retaining part 27′11 has an obtuse-angled triangular cross-section, wherein the outer angles opposite the obtuse angles face the beam slab column through which the middle beam slab settlement groove 27′1 passes through the groove 24. This arrangement makes it less likely for the inner beam slab column protective layer 321′1 with the retaining part, which is bonded to the middle beam slab settlement groove 27′1, to detach from the concrete frame structure in the direction away from the column, thereby enhancing the structural consistency between the protective layer and the column.

[0150] Overall, the inclusion of matching reinforced concrete retaining sections and protective layer bonding surface retaining sections increases the adhesion force of the protective layer bonding surface to the reinforced concrete frame structure, which helps reduce the cracking degree of column assembly 1 and beam-slab assembly 2. The reinforced concrete retaining section within the concrete frame settlement section enhances the protective strength of the protective layer assembly 3 for the concrete frame structure, effectively improving the stability of the bond between the protective layer bonding surface and the reinforced concrete structure, and strengthening the protective effect of the protective layer assembly 3 on the concrete frame structure.

[0151] The reinforced concrete retaining part is a structure with an uneven shape installed on the surface of the settlement section of the concrete frame. Optionally, the reinforced concrete retaining part can be a raised structure with a straight line, a curve, or scattered points in its planar projection.

[0152] The right-angle protective layer can effectively save the ECC material of the protective layer component 3 while fully protecting the concrete frame structure.

[0153] Example 2

[0154] A concrete frame structure with a rounded corner protective layer.

[0155] The protective layer material is ECC, which has an equal wall thickness structure; the rounded corner structure protective layer refers to the rounded corners at each edge after multiple planes that make up the protective layer intersect perpendicularly.

[0156] The concrete frame structure with a rounded protective layer and an ECC material layer in Example 2 is based on the concrete frame structure with a right-angle protective layer and an ECC material layer in Example 1. All the edges at the junctions of floor slabs, beams, and columns in the settlement section of the concrete frame are rounded, so that the ECC material layer filling the settlement section of the concrete frame has a corresponding chamfered structure, which enhances the protective effect of the ECC material layer on the concrete frame structure and helps to improve the service life of the concrete frame structure.

[0157] Specifically, in this embodiment 2, the edges of the settlement part of the rounded concrete frame at the intersection of all floor slabs, beams and columns in pairs / three-sided intersections are designated as key edges, and chamfers are provided on all key edges, specifically rounded corners.

[0158] like Figure 20 As shown, the concrete frame structure with a rounded corner structure and an ECC material layer includes a rounded corner column assembly 1-1, a rounded corner beam and slab assembly 2-1, and a rounded corner protective layer assembly 3-1.

[0159] The rounded corner column assembly 1-1 includes rounded corner corner column 11-1, rounded corner side column 12-1, rounded corner middle column 13-1 and rounded corner base column.

[0160] The rounded corner beam and slab assembly 2-1 includes a rounded corner floor slab 21-1 and a rounded corner beam 22-1.

[0161] The rounded corner protective layer assembly 3-1 includes a rounded corner beam and slab protective layer assembly 31-1 and a rounded corner beam and slab column protective layer 32-1.

[0162] The rounded corner beam and slab protective layer assembly 31-1 includes the rounded corner side upper beam and slab protective layer assembly 312-1.

[0163] like Figure 22 As shown, the rounded corner beam-slab-column protective layer 32-1 includes the rounded corner inner beam-slab-column protective layer 321-1 within the concrete frame structure and the rounded corner outer beam-slab-column protective layer 322-1 on the outer periphery of the concrete frame structure.

[0164] Both the rounded corner column assembly 1-1 and the rounded corner beam and slab assembly 2-1 are equipped with rounded corner concrete frame settlement sections.

[0165] Only with Figure 20 Taking the structure in region D as an example, the following describes a concrete frame structure with a rounded corner protective layer and an ECC material layer:

[0166] Combination Figure 20 and Figure 21 As shown,

[0167] Example 2 is based on Example 1, in which the edges of the concrete frame settlement section are rounded.

[0168] Specifically, in Embodiment 1, the first upper beam edge settlement groove 25 and the second upper beam edge settlement groove 28 of the beam-slab assembly 2 are connected to form the rounded upper beam edge settlement groove 23-1 at the top of the rounded corner beam-slab assembly 2-1 in Embodiment 2. In Embodiment 2, a rounded corner side beam-slab settlement groove 26-1 is provided on the outer facade of the rounded corner beam-slab assembly 2-1, and a rounded middle side beam-slab settlement groove 27-1 is provided on the inner facade of the rounded corner beam-slab assembly 2-1.

[0169] The key edge of the rounded upper beam plate edge settlement groove 23-1 is provided with a rounded upper beam plate edge settlement groove chamfer 23-11.

[0170] The rounded corner side beam plate settlement trough 26-1 and the rounded corner side column 12-1 are connected. The key edges of the connected settlement trough structure are provided with rounded corner side beam plate settlement trough chamfers 26-11. The rounded corner side beam plate settlement trough chamfers 26-11 are distributed on the rounded corner side beam plate settlement trough 26-1 and the rounded corner column 112-1.

[0171] The rounded corner middle side beam plate settlement groove 27-1 and the rounded corner column settlement groove 111-1 are connected. The structure of the connected settlement groove forms 3 intersecting key edges. After the 3 intersecting key edges are rounded, the connected rounded corner middle side beam plate settlement groove chamfer 27-11 is formed.

[0172] Corresponding to the rounded corner structure of the rounded corner side column 12-1 and the rounded corner beam-slab assembly 2-1, in Figure 20 The rounded corner protective layer assembly 3-1 in region D includes a rounded corner center upper beam plate protective layer 311-1, a rounded corner side upper beam plate protective layer 312-1, and a rounded corner corner upper beam plate protective layer 313-1, which are integrated into a whole.

[0173] like Figure 22 As shown, the ECC material layer of the rounded corner protective layer component 3-1 is filled with the settlement part of the rounded corner concrete frame with the same wall thickness. A chamfer 312-11 is formed on the rounded corner side upper beam slab protective layer 312-1, a chamfer 321-11 is formed on the rounded corner inner beam slab column protective layer 321-1, and a chamfer 322-11 is formed on the rounded corner outer beam slab column protective layer 322-1.

[0174] Since the settlement groove 23-1 on the rounded corner upper beam plate and the settlement groove 26-1 on the rounded corner side beam plate are connected, the protective layer 312-1 on the rounded corner side plate and the protective layer 322-1 on the rounded corner outer beam plate column of this embodiment 2 are bonded together.

[0175] The rounded corner protective layer can effectively reduce stress concentration at the right angle of the concrete frame settlement part and the protective layer component 3, and further enhance the crack resistance and durability of the concrete frame structure with protective layer.

[0176] Example 3

[0177] A construction method for a concrete frame structure with a protective layer.

[0178] This embodiment 3 uses a concrete frame structure with an ECC material protective layer as an example to introduce the construction method.

[0179] A construction method for a concrete frame structure with an ECC material protective layer is as follows:

[0180] S1. Preparations:

[0181] Preparatory work includes establishing the foundation of the concrete frame structure. This includes: site leveling, setting up a control network, earthwork excavation, foundation pit support, pile foundation construction, subbase layer, and waterproofing. It also includes foundation construction work such as foundation reinforcement binding.

[0182] S2. Construct the bottom installation formwork with protective layer spacer blocks and pour concrete:

[0183] S21. Install the underlying template:

[0184] The installation of the bottom formwork includes binding column reinforcement bars, erecting scaffolding, installing the bottom formwork of the bottom of column assembly 1 and bottom beam and slab assembly 2, binding beam reinforcement bars, installing the bottom side of column assembly 1 and the installation formwork of bottom beam and slab assembly 2, and binding the reinforcement bars of bottom beam and slab assembly 2.

[0185] S22. Place protective layer spacers on the inner wall of the installation template for column assembly 1 and beam-slab assembly 2:

[0186] ECC protective layer spacer blocks are placed at fixed points on the side facades of column assembly 1 and beam-slab assembly 2 on the inner wall of the installation template. That is, protective layer spacer blocks are placed on the concrete frame structure corresponding to the beam-slab-column protective layer unit 32. Preferably, the outer wall of this part of the ECC protective layer spacer block is provided with a matching structure of reinforced concrete retaining part.

[0187] S23, pouring concrete for foundation column 14 and bottom beam-slab assembly 2:

[0188] Concrete is poured into the installation template to form the concrete structure of the foundation column 14;

[0189] After the bottom layer of reinforced concrete frame structure is formed, the installation formwork and the protective layer spacer blocks on it are removed; the concrete frame structure formed includes the concrete frame settlement part on the side facade of column assembly 1 and beam-slab assembly 2.

[0190] S24. After the initial setting and before the final setting of the concrete formed in S23, a settling groove 23 in the middle of the upper beam slab, a settling groove 26 on the side beam slab, and a settling groove 27 on the middle side beam slab of the bottom beam slab assembly 2 are pressed out on the concrete of the floor slab at the top of the bottom beam slab assembly 2 using a mold that matches the structure of the beam slab protective layer unit 31, forming a concrete frame settlement part at the top of the floor slab of the bottom beam slab assembly 2; preferably, the outer surface of the mold that matches the structure of the beam slab protective layer unit 31 is provided with a structure that matches the retaining part of the reinforced concrete settlement part.

[0191] S3, Fabrication of the protective layer assembly for ECC material 3

[0192] Spray or trowel ECC material layers onto each concrete frame retaining part to form multiple protective layer components 3 protective layer units;

[0193] Each protective layer unit is a protective layer with the same wall thickness as itself;

[0194] Before the concrete sets, place an ECC protective layer mold on the concrete frame retainer with an ECC material layer.

[0195] After the ECC material layer is characterized, the ECC protective layer mold on each protective layer unit is removed, and the ECC material protective layer assembly 3 is flush with the outer surface of the concrete frame and forms an integral whole.

[0196] S4. Repeat steps S2-S3 to complete the construction of the concrete frame structure with ECC material layers from the second floor to the top floor.
